Abstract :
In this paper, experiments of an all-solid-state insulated semi-insulating GaAs ultrafast surface photoconductive semiconductor switch triggered by nanosecond and femtosecond laser are reported. Both linear and nonlinear modes of the 3 mm-gap GaAs PCSS were observed when triggered by the μJ nanosecond laser. The current could be as high as 560 A. The same device also revealed good temporal characteristics when triggered with a 76 MHz femtosecond laser. The rise time of the PCSS response is less than 200 ps, and is limited by the coaxial cable
